IMPROVEMENT IN BUTTER-WORKERS.

Specification forming part of Letters Patent No. 115,144, dated May 23,1871.

Nature of the Invention.

This invention is animprovement upon that patented to meMarch 19, 1861. It consists in an arrangement, of sla-ts combined with the reciprocating butter-board and roller for producing a vertical adjustment at said board, at either or both ends, without changing the position of the roller or its racks, in the manner and for the purpose hereinafter set forth.

General Description. In the drawing, Figurel is a plan ot' my im provemeat; Fig. 2, a longitudinal vertical secpinions l 1 at each end, which engage with racks 2 2 of the frame, and it is driven by a crank, a. This arrangement is also the same as in my aforesaid patent, except that I now make the racks xed and stationary instead of movable, as in the former case. Ind this necessary in order to give freedom of. action to the roller and prevent any irregularity or j looseness as it moves from end to end.A The table or butter-board stands in an inclined di- A rection to readily run ott the butter-milk or whey, and at opposite ends it rests upon crossslats I) l) or equivalent, by which it is sustained. These slats have vertical slots b b, with screws c c passing through, or are otherwise arranged so that a vertical adjustment of the butter-board under the roller may be given at either or both ends without changing the position of the roller or the racks in which it runs. My invention consists inthis method of adjusting the butter-board without affect-` ing the roller or racks. It places the board entirely under control, so as to be moved up bodily at both ends to accommodate a greater or lesser quantity of butter 5 or to be moved up at one end higher than the other to accommodate the difference in discharge; or to be set up at one side higher than the other to prevent any undue working or acculnulation of the butter laterally.

As the slats extend entirely across the butterlboard and are adjustable each at both ends, it will be seen that all these adjustments are easily attained. It there is anyinequality or warping of the board at any time, produced by swelling or contraction, the slats may be adjusted to t it.

An important result of my improvement consists in producing the adjustment without af fecting the roller or the racks in which it runs. It is difficult, if not impracticable, to change the adjustment of the latter, for the reason that both racks cannot be brought to the same position or incline. If they are out of line it produces a binding in the gear. Neither can they be adjusted to give a different longitudi nal pitch to the roller on the bed.

I am aware that in other forms and kinds of butter-workers the rolling dish or basin is adjusted up by means of a screw. SuchIdo not claim. Neither do I claiml adj usting-slats, except as they are combined with the table and roller.

What I claim, and desire to secure by Letters Patent, is- .j

The arrangement of the adj usting-slats D D, reciprocating table A, and vibrating roller B moving on the xed racks 2 2, the whole constructed and operating substantially in the manner and for the purpose set forth.

In witness whereof I have hereunto set my my hand this 14th day of December. 1870.

G. WOODARD.
